Px8 was a good buy in my opinion if you could pick it up for the 550 Price Mark. And that's as a whole package. I'm not sure which sub $200 headphones sound better but there is a domain of lower construction quality is headphones such as the shure aonic that might sound better than the PX8.
Ultimately you have to try it yourself to decide. Without knowing which headphones in particular and not having tried the momentum 4 It's hard for me to judge what resolve is saying from personal experience. What I can do is say that at least to my ears the PX8 were a significant improvement over the PX7 to the point that I would consider them enjoyable to listen to though not ideal from the options available
In particular the way in which they create a sense of with and depth sounds very veiled to my ears. This is less severe than the PX7s which I completely stopped using after I heard the moon drop blessing twos. However the focal with EQ had a comparable if not better soundstage without the veiling effect.
